In a fast-paced and entertaining novel with a superlatively romantic premise, 17-year-old Hadley misses her flight to London, where her father is marrying the woman he left their family for, but she unexpectedly may have found true love in the process. When Hadley meets charming Oliver at the gate, they instantly connect and bond during her new flight. They even share a kiss in the customs line, but Hadley loses sight of him afterward. Now, she has to survive being a bridesmaid, contend with her feelings about her father’s new life, and figure out how to find Oliver before she returns to the U.S. the next day. Hadley is rushing through most of this book, and readers will gladly race alongside her. But they’ll also savor cinematic moments, like a touching heart-to-heart conversation between Hadley and her father on the dance floor. Smith (You Are Here) balances Hadley’s dual relationship dramas well, and while the story wraps up neatly, readers will be as caught up as Hadley is by the physical and emotional distances she traverses. Agent: ICM. Ages 12–up. (Jan.)
